HI Larry: Was advised to using Hollow Core braid with a FG knot to the shock leader for casting my huge GT poppers. Have you heard of using knots with hollow core braid? Any advantage over non hollow braid if not running the mono through the hollow core?

Other than for making wind-on leaders I prefer non-hollow core as the diameter per pound test is lower, also I've had a few issues with power pro hollow core where there are sometimes random "blemishes" in the braid where a fatal weak spot will occur.It's slicker, but thicker so I don't see it as an advantage for most applications.bestL
